The present invention relates to a notification device of an elevator.

In recent years, many apparatuses for improving the use environment of elevators, which are transportation systems in buildings, have been used. In particular, there is an increasing tendency for devices to inform passengers by sound. For example

(a) Voice guidance

(b) Registration Tone at Call Registration

(c) Chime indicating arrival of destination class

(d) Buzzer warning when the load exceeds the load

(e) Buzzer sounds indicating the closing of the door.

These devices are configured with individually independent functions.

As an example, FIG. 1 shows a notification device provided in the elevator elevator 1.

The above-mentioned (a) consists of the voice guidance apparatus 2 IC integrated by the audio waveform formation method (ADPCM, ADM, etc. data compression method), and arrange | positions the speaker 3 on an elevator room, and sends a message to a passenger. Informed. The above-mentioned (b) is called the pronunciation buzzer (4) and informs the fact that the elevator call button 9 is pressed, and is installed in the lower part of the elevator operating panel (5). Piezoelectric buzzers are often used as elements.

The above-mentioned (c) is the electron chimes 6A and 6B, and are installed above and below the lifting chamber 1, respectively.

Since the above-mentioned (d) is a warning function as the overload buzzer 7, the volume to be surely heard by the passenger is required. The above-mentioned (e) is the door close acceleration buzzer 8, and an electronic buzzer is often used.

As described above, since the apparatus is composed of individual apparatuses, it is required to generate different sounds.

In particular, (d), which is conventionally employed in elevators, is provided above the elevator, (c) is installed above and below the elevator, (a) the speaker is installed above the elevator, and (b) is installed in the elevator operating panel. have.

Many of these devices are often attached according to customer specifications, and are to be installed every time. Therefore, some of these notification devices are installed in a general elevator. In addition, as can be seen from Figure 1, these devices are often installed on the hoist room, there is a problem that requires a large space.

In recent years, a number of devices for improving the use environment have been used in elevators, which are longitudinal transportation organs of buildings. This is because the elevator is not only functioning as a transportation engine but also as an important facility in a building, so that the human interface function for the user is required to be faithful.

In particular, the voice notification function is an excellent function for the user to perform various broadcasts.

This is not only a conventional notification such as an elevator arrival notification (eg, 1st floor, 2nd floor) or door opening / closing notification (eg, the door is closed), but also a voice when the user has difficulty in operation. The function of informing was faithful. This is called state announce and has been installed in the majority of elevators.

The announce of this state makes it possible to cope with the case where the user cannot know the operation and when the elevator has an abnormality as described above. For example, in the case of 10,000 won, it is 10,000 won. When you need to re-register for the last minute call, press the destination floor button again. In the event of an error, please wait for a while.

In addition, a voice synthesis method for recovering the voice data stored in the IC is adopted for these voice notification functions.

Since the voice sum growth value of elevators is often installed in elevator elevators and elevator control devices that output voice commands are installed in the machine room of buildings, signals between them are controlled by the serial transmission method.

In general, the number of voice messages is about 30 messages, and the number of signals about 50 points is required if other control commands are included. When these signals are sent and received in parallel, the number of wires required is 50, and not only the number of wires is increased, but the number of wires is 50, and the interface device for receiving these wires is increased, so that the number of wires is increased by about two wires by serial transmission. I'm in control. In general, this serial transmission method is often adopted by RS 485 in accordance with the IEEE standard, and has a serial bus structure using an elevator control device as a booster.

Moreover, what is called a twisted pair wire is used for the electric wire used. However, since serial transmission is less reliable than parallel transmission, important signals such as abnormal signals of elevators are processed by parallel transmission.

Next, the configuration of the speech synthesis apparatus 10 will be described with reference to FIG.

The voice synthesizing apparatus 10 receives a general signal from the serial transmission control section 11 and an important signal from the parallel transmission control section 12 from the control device in the elevator machine room as shown in FIG. The CPU 13 interprets the data according to the procedure stored in the storage unit 14 and instructs the voice synthesis unit 15 to issue a voice guidance message command.

The speech synthesis section 15 reads out the speech data stored in the speech data storage section 16 at sampling time intervals according to the speech synthesis method, performs D / A conversion, and then outputs the speech data to the speaker 17. In this example, the speech synthesis section 15 is a processing system having an LPF (low pass filter) function and a speech amplification function.

3 shows a case in which the audio synthesizing apparatus 10 is provided on the operation panel 19 of the elevator cabin 18. The operation panel 19 includes buttons for generating an operation command of the elevator (cab call button 20, door opening button 21, door closing button 22), elevator position indicator 23, interphone 24, and the like. It consists of. Here, the interphone 24 is the only contact device that can request rescue in case of an elevator failure, and the elevator passenger can communicate with the manager of the building via the interphone microphone 26 by pressing the interphone 25 in an emergency. .

The voice guide speaker 27 of the voice synthesis device 10 should be provided with a hole for making a sound in the front of the voice guide speaker 27, and is arranged in parallel with the interphone speaker 28 of the interphone 24 at the design surface. In many cases, the elevator passenger has a form that looks like a large interphone speaker 28 is provided.

As mentioned above, although the conventional elevator aims to inform passengers, there are cases where it is not always satisfactory for passengers because a sound is generated from the devices installed in each place.

For example, since the voice message of the voice guidance is output from the speaker 3 on the elevator, it may be difficult for the passenger to hear the sound from the head direction.

In addition, there is a drawback that the sound is influenced by the mechanical structure of the hoist room.

The notification of the registration sound at the time of call registration is the sound of the fact that the elevator call button has been pressed, but this device is often installed under the elevator operating panel 5, compared to the operation of pushing the elevator call button 9. Sound is output from the bottom.

Destination arrival chimes (6A, 6B) may inform passengers waiting for the platform along with passengers in the cabin.The chime (6A) above the cabin sounds when driving up and the chime (6B) below the cabin when driving down. It is supposed to ring.

As described above, there is a problem that the conventional apparatus is not necessarily arranged for passengers.

Although the voice synthesizer of the elevator is constituted as described above, the message is not appropriate depending on the timing of the signal because it is controlled by two types of signal transmission methods.

This is largely due to the mechanism of generating an abnormal signal of the elevator. That is, the abnormal signal of the elevator outputs the abnormality of the elevator itself, but is not necessarily limited to the occurrence of the abnormality.

Generally, abnormalities of an elevator can be classified into several types shown below.

(a) Operation of safety circuit-complete failure

(b) Abnormal-returnable faults in signal conditions

(c) Failure that can be recovered depending on the abnormal state of the control signal

(d) Abnormal-returnable faults in operation.

(e) The device may not be fault-determined.

(a) is a state in which the safety circuit owned by the elevator operates to absolutely stop the elevator. The abnormal signal in this case can be clearly defined.

(b) is a failure mainly caused by the elevator usage condition, and occurs when the user's clothes are stuck in the door or when the door is opened while driving with mischief. In this case, if the condition returns, normal operation is possible. Therefore, it is not possible to determine when the elevator control apparatus can return.

(c) is a case where an abnormality is detected in the rationality of the apparatus required for driving an elevator, and is performed by comparing, for example, the signal state of the switch which allows the door to be opened and the signal state of the switch which commands the leveling.

Therefore, in (b), (c), and (d), the recovery time of the abnormal signal cannot be predicted. Therefore, simply outputting a parallel signal often makes the message content inappropriate.

Although the voice synthesis apparatus 10 of the elevator is configured as described above, there is a problem in that the emergency intercom 24 and the general voice guidance speaker 27 are affected acoustically.

The voice guidance is to perform the above-mentioned broadcasting by voice, but when a situation arises in which the interphone 24 should be used regardless of the mode, the voice guidance speaker 27 is generated by the interphone microphone 29 of the interphone 24. There is a significant drawback in that the voice input is returned and cannot be entered into the call situation of the buffer interphone 24.

This will be explained below.

The structure of the interphone 24 is shown in FIG.

The interphone 24 is composed of an interphone speaker 28, an interphone microphone 29, a voice amplifier 30, and a voice switch 31. The interphone 24 used in the elevator cab 18 does not have a handset such as a telephone, and the interphone speaker 28 and the interphone microphone 29 are attached to a position close to each other. Conversation is made toward the microphone 29.

In this case, when the sound output from the interphone speaker 28 is input to the interphone speaker 29, a housing phenomenon occurs, and the sound generated from the interphone speaker 28 becomes a key-in sound.

In order to avoid this, the circuit configuration which measures the volume of both directions of a call by the voice switch 31, and prioritizes the louder sound is taken. Therefore, the interphone 24 has a structure in which the sound in the direction is not transmitted to the counterpart side when only the call of the louder side is made and the sound is smaller.

Therefore, when voice guidance is executed when the interphone 24 is to be used, the interphone 24 cannot be talked on.

In general, since the voice guidance time is several seconds, this is not a problem. However, it is conceivable that the instruction to the voice guidance apparatus 10 becomes abnormal when an elevator malfunctions. In this case, the voice is continuously broadcast. There is.

In addition, the voice guidance speaker 27, the interphone microphone 29, and the interphone speaker 28 are provided in parallel with the surface plate (called the faceplate) of the operation panel 19. As shown in FIG. The voice guide speaker 27 is in the voice output state by a voice amplifier or the like of the voice synthesis processing section in the voice synthesis device 10.

For this reason, the voice guidance speaker 27 always has a small drive output, and there is a drawback that the vibration is input to the interphone microphone 29 through the face plate. Since this vibration also varies depending on the installation state of the elevator elevator, it is difficult to make the state of the interphone 24 the best.

In addition, it is necessary to perform voice control under a bad condition that a plurality of speakers which are different from a microphone are completely different from a microphone, and that it is sealed like an elevator cabin. Since the elevator cabin itself is made of metal, the acoustic coupling degree is high. The vibration problem is important.

It is an object of the first invention to provide a voice synthesis apparatus for an elevator which solves the above-mentioned conventional problems and can provide sufficient information to a passenger and leave no complaints.

Moreover, a 2nd invention aims at solving the above-mentioned conventional problem and providing the apparatus which can inform an elevator user of reliable information.

Moreover, the 3rd invention aims at solving the conventional problem as mentioned above and providing the voice synthesis | combining apparatus which can reliably operate the interphone used for emergency.

A first means for solving the problem will be described below.

The present invention has a configuration in which the speech synthesis waveforms can be mixed, and the apparatus having the centralized function can be provided by equipping each of the storage units with sound data of a corresponding sound source.

This configuration is shown in FIG.

The present invention provides a sound source data storage unit 32 storing a plurality of sound source data, a data recovery unit 33 having a means for restoring the plurality of sound source data, a waveform synthesizing unit 34 for synthesizing the sound source data, and a passenger. And an amplifying section 35 for holding, an output section 36 for converting waveforms to sounds, and a sound source selecting section 37 for reproducing sound source data by decoding sound source commands from an elevator control device. In the configuration of the present invention, the device is intended to be stored in the elevator operating panel 5 and to notify passengers in the elevator. Therefore, it is necessary to miniaturize the device.

Therefore, as a specific example of the above configuration, the sound source data is often composed of ROM having a high degree of integration. As a means for reproducing the sound source data, reproducing means such as ADPCM, PCM, ADM and the like are well known. As these sound source reproduction means, the amount of memory required for reproduction of the sound source is about 64 Kbit / sec.

Generally, 2 Mbits of ROM capacity is generally obtained, and when this is calculated, about 32 sec of voice can be stored.

Next, the second means will be described.

The present invention is configured such that the contents of the announces are accurate even in the event of an abnormality in elevator operation.

This configuration will be explained using FIG.

FIG. 6 adds the process of the present invention based on FIG.

In FIG. 6, the storage unit 14 is divided into a general information storage unit 14A and an important information storage unit 14B, and a serial transmission error detection unit 38 is added. In other words, when the serial transmission is normal, the important information storage unit 14B does not operate, and the voice synthesis process is performed by the serial transmission control unit 11, the general information storage unit 14A, the control CPU 13, and the like. That is, in the range where the serial transmission can be normally operated, the elevator control device transmits all announce signals including abnormal information.

As a result, the general information can be managed by all the elevator control unit CPUs in the elevator machine room, thereby eliminating the abnormal announce timing seen in the conventional configuration.

However, even in this case, an abnormality in congestion or the like of the elevator controller CPU cannot be managed. However, according to the present invention, since an abnormality in serial transmission is detected and the management is handled by a parallel transmission signal, it is possible to announce even at this abnormality.

The timing chart according to the present invention is shown in FIG. 7 in order to explain the above operation condition in detail. In this figure, the serial signal which is the output result of the serial transmission control section 11, the parallel signal which is the output result of the parallel transmission control section 12, the serial transmission error signal which is the output result of the serial transmission failure detection section 38, and the speech synthesis section 15 The waveform of the announce which is the output result of) is described.

Step 1 shows a case where a command by a serial signal occurs while the serial transmission state is normal and the parallel signal is OFF.

At this time, the control CPU 13 instructs the announce command to the voice synthesizing unit 15 by the procedure by the general information storage unit 14A.

As a result, an announce corresponding to the serial signal is executed.

Step 2 shows the case where the serial transmission is normal but the parallel signal is turned ON.

Conventionally, the announce by the parallel signal is performed at this time, but the announce is not performed in the present invention. This is because the serial transmission error detection unit 38 does not output the command to the important information storage unit 14B, so that the result of the parallel transmission control unit 12 is not transmitted to the control CPU 13.

Step 3 shows that a command by a serial signal is generated in the state of Step 2.

In this case, announce by a serial signal is performed as in step 1.

Step 4 shows a case where a serial transmission error is detected in the state of Step 2.

At this time, announce by a parallel signal is executed.

Next, the third means and the fourth means will be described.

The third means will be explained using FIG.

8 is a longitudinal cross-sectional view of the operating panel 19 in the elevator cabin 18. The interphone 24 and the voice guidance speaker 27 are provided in the operation panel 19 or the speaker case 39 in the operation panel 19 is outside the range of the directivity characteristic of the interphone microphone 29 in the attachment of the voice guidance speaker 27. By attaching the voice guide speaker 27 sealed by), the sound generated by the voice guide speaker 27 does not affect the operation of the voice switch 31 of the interphone 24.

In the fourth means, since the voice guidance speaker 27 is provided behind the interphone 24, the influence of the voice guidance speaker 27 does not appear in the interphone microphone 29. In addition, since the interphone speaker 28 is not attached to the surface plate of the elevator operating panel 19 and is installed with a space of about 2-3 mm, the sound of the voice guidance speaker 27 is lifted in the elevator lift room ( 18) is configured to be output.

In the third means, since the voice guide speaker 27 is provided outside the directivity range of the interphone speaker 29, the sound of the voice guide is not directly input to the interphone speaker 29. Therefore, the voice control in using the interphone 24 is controlled only by the voice of the elevator passenger and the conversation voice of the manager of the building which is the other party.

In addition, in the present invention, since the voice guide speaker 27 is closed by the speaker case 39 in the present invention, the influence of the voice guide speaker 27 is also reduced, so that the voice guide speaker 27 can be announced with good sound quality.

In the fourth means, since the voice guidance speaker 27 is provided behind the interphone 24, the voice or vibration from the voice guidance speaker 27 can be made independent of the interphone microphone 29.

In general, the speaker deteriorates the sound quality if it does not float toward the outside of the face plate of the operation panel 19, but in the present invention, the sound guidance speaker 27 is closed by the speaker case 39, so the deterioration of sound quality is small. On the contrary, since the performance of the interphone 24 is the same as before, the overall performance is improved.

In addition, in this means, the voice guidance speaker 27 does not appear on the surface of the operation panel 19, and there is an effect that no restriction is imposed.

An embodiment of the first aspect of the present invention will be described.

In recent years, the audio synthesizing apparatus in elevators is stored in an operation panel in an elevator cabin. This is because the voice output for the passenger in the hoist room can be uttered at the height of the passenger's ear when the voice output is output from the upper part of the operation panel, so that the configuration can be easily understood.

In this case, the external shape of the apparatus can be about 100 mm x 100 mm x 20 mm, and the speaker for audio output can be integrated. In this embodiment, as shown in FIG. 9, the control CPU 40, the voice synthesizing units 41, 41A, 41B, 41C, the audio data storing unit 42, the mixing unit 43, and the speaker 3 are constituted. It is.

The control CPU 40 receives a broadcast command from the elevator control device, and performs a function of converting the received data into the voice synthesizer 41 for data conversion.

The voice synthesizing section 41 has a function of reproducing by the ADPCM method as described above.

Therefore, the voice synthesizer 41 reads the digital data stored in the voice data storage 42 at the sampling interval, converts the analog data into analog data, and outputs the analog data to the mixing unit 43.

In general, however, the sampling frequency is 16KHz in ADPCM, so it is sufficient to read data at about 60 microsecond intervals.

At this time, since the data read time of the CPU is generally about 500 nanoseconds, it can be seen that there is about 100 times as much spare time.

This timing chart is shown in FIG.

In FIG. 10, the control CPU 40 reads data from the voice data storing unit 42 and instructs each of the voice synthesis units 41A, 41B, and 41C, and timings the output of each voice synthesis unit, that is, the voice waveform. I express it in a chart. The control CPU 40 reads data from the audio data storing unit 42 in synchronization with the sampling cycle.

Since the audio data storage section 42 is composed of a storage device such as a ROM, it is generally a processing system equivalent to a balance of a microcomputer circuit.

As a matter of course, since the control CPU 40 reads out data for the sampling time, it can be completed with one byte of data. The time required for this is 500 nanoseconds described above. It is 60 microseconds later that the data needs to be supplied to the speech synthesis unit A after the sampling time, so that the control CPU 40 has sufficient spare time.

Using this, data is output to the voice synthesis sections 41B and 41C to obtain the timing chart of FIG.

By using this, a plurality of broadcast contents can be output at the same time.

In the present invention, the voice message and the sound for other alarms may be output at the same time, so that a voice message requiring a relatively long time control is preferentially processed, and other alarm sounds can be processed in a short time.

For reference, the number of times of accessing the audio data storing unit becomes 200 milliseconds in the shortest in the case of an alarm sound.

In addition, as a place where this apparatus is actually installed, it becomes the form similar to FIG. 11 stored in the operation panel 5. FIG. 11 is an enlarged view of only the operating panel 5 of FIG. 1 and is provided on the upper part of the boarding room call button 9.

This position is about 1300 mm above the floor of the elevator cabin, making it easy for passengers to understand.

A flowchart for carrying out the above-described processing is shown in FIG.

12 shows the processing procedure of the control CPU 40, and shows the processing contents of the storage unit 44. FIG.

Step 121 means a process in which the control CPU 40 reads the contents of the data receiving unit 45 that receives an instruction from the elevator controller.

Step 122 to step 126 show the processing contents of the audio synthesis section 41A.

In step 122, it is determined whether or not the message A output from the audio synthesis device 41A is being output to the mixing section 43. If the message A is not output in this step, the voice synthesis initial step following step 122 is executed. If output is in progress, the sampling process after step 125 is executed.

Since it is determined in step 123 that the message A is not output, it is determined whether or not there is a message output command calculated in step 121. If no message output is specified here, the processing proceeds to the processing system of messages B and C after 127. Step 124 is a process of initializing the sampling time when the message output command is first generated. Sampling time is a basic time interval for synthesizing speech, and is set to 60 microseconds in this embodiment.

This indicates that the processing procedure of FIG. 12 should be completed at a maximum of 60 microseconds.

In general, when one execution time of the control CPU 40 is converted to one microsecond, the processing needs to be completed in about 60 steps. As a result, the limit of three messages is the limit of the present invention.

In step 125, this sampling time is determined. If it is during this time, the audio data storing unit 45 reads out the audio data and outputs the data to the voice synthesizing unit 41A (step 126).

Step 127 is a process for message B, and step 128 is a process for message C.

According to the present embodiment, the voice synthesizer stored in the elevator operating panel allows voice messages, passenger call registration sounds, image chimes, alarm buzzers, etc. to be viewed only by the device, and is easy for passengers to accept. Since the voice can be output from the height, it is possible to provide passengers with superior functions compared to the conventional configuration.

In addition, since each sound is placed in the electronic voice data storage unit, it is possible to maintain a constant sound quality at all times, so that there is no change over time such as deterioration of sound quality as in the prior art.

In the above embodiment, an example is provided in the elevator operating panel, but of course it is also easy to install in the elevator platform.

In this case, an arrival chime may be output at the same time as a voice message of the arrival time of the elevator for the passenger waiting for the elevator.

As an extension of the above example, it is also possible to simultaneously process not only the autonomous message but also other tag messages.

Next, examples of the second aspect of the present invention will be described.

An embodiment employing the present invention will be described using FIG.

In recent years, the audio synthesizing apparatus 10 in elevators is incorporated in the operation panel 47 in the elevator elevator 46.

This is because the voice output for the passenger 48 in the cabin can be spoken at the ear level of the passenger 48 when it is output from the upper part of the operation panel 47, so that the configuration can be easily heard. Therefore, as the place, the place below the elevator position display device 49 or above the elevator cab call button 59 is optimal.

In this case, the external form of the speech synthesis apparatus 10 needs to be about 100 mm x 100 mm x 20 mm in size.

In order to realize this, it is assumed that the audio output speaker 17 is integrated. Therefore, in the embodiment, as shown in FIG. 14, the control CPU 13, the audio data storing unit 16, the speaker 17, the storage unit 14C according to the present embodiment, the serial transmission control unit 11, and the parallel It consists of a signal control part 12.

The control CPU 13 receives a broadcast command from the elevator controller, converts the received data into the voice synthesizer 15, and performs a function for serial transmission. CPU is used.

The voice synthesizing unit 15 has a function of reproducing by the ADPCM method as described above.

Therefore, the speech synthesis section 15 reads the digital data stored in the speech data storage section 16 at sampling intervals, converts the analog data into analog data, and outputs the analog data. The serial transmission control unit 11 is composed of an interface IC conforming to the RS485 standard and an IC for serial control.

In this embodiment, the serial bus by the cyclic scan method will be described as serial transmission. The cyclic scanning method is a time-division multiple parallel method adopted in general microcomputers, which is a serialized configuration. Each device connected to the serial bus detects its own address by alternately placing an address and data on the serial bus. To read and write data. 15 shows a transmission state diagram according to the present method. FIG. 15 shows the data state on the serial bus, and shows that the address and data are transferred alternately.

Generally, this data frame is referred to as auxiliary synchronization, and is composed of start bits, data bits, parity bits, and stopper bits.

In this example, this is composed of 12 bits.

In such a serial transmission method, it is necessary for the control CPU 13 to monitor the serial transmission control unit 11 at all times. For this reason, the storage unit 14C is composed of announce processing, serial transmission monitoring, and parallel signal processing, that is, three blocks, and the control CPU 13 performs the processing of the embodiment in accordance with these procedures.

In this embodiment, the abnormality detection of serial transmission is performed by the serial transmission monitoring routine in the storage unit 14C. Accordingly, in the cyclic scanning method, it is determined that there is an error in serial transmission when the address cannot be received for a predetermined time or more by using a feature in which an address for selecting the device itself is transmitted at a predetermined cycle.

The flowchart for performing the process as mentioned above is shown in FIG.

16 shows the processing procedure of the control CPU 13, and shows the processing contents of the storage unit 14C.

Step 160 is a process in which the control CPU 13 reads the contents of the serial transmission control unit 11 that receives an instruction from the elevator controller, and indicates whether or not the address to which the speech synthesizer 10 is assigned is received. .

In addition, in step 161, step 162 shows the content of general time, and is the process of the conventional audio | voice synthesis apparatus 10. In FIG.

Step 161 shows a process of resetting the serial transmission error timer because the address of the speech synthesis apparatus 10 has been received.

Step 162 shows reading data transmitted after the address of the speech synthesis device and executing an announce according to the command.

That is, the control CPU receives data from the serial transfer control unit 11 and generates an announce command to the speech synthesis unit 15. The speech synthesis section 15 reads out the digitalized data from the speech data storage section 16 at sampling time intervals and converts the data into analog data according to the ADPCM procedure.

If the result is output to the speaker 17, it is an announce to the passenger.

Step 163 shows the procedure when the address could not be received.

Since the cyclic scan method generally uses a transmission method of one cycle of about 100 msec, if the address could not be received even after 500 msec, it is determined in step 164 that the serial transmission is abnormal. In the case of less than that time, it is regarded as normal and the routine is not executed.

Naturally, this time value is different depending on the system.

In step 164, it is determined that there is an abnormality in the serial transmission. Therefore, the parallel transmission control unit 12 performs a process of reading data. Since the parallel transmission control part 12 receives the signal by a contact, the received data turns into execution instruction as it is.

Step 165 is a process of converting a parallel signal into an announce command and is executed in the same process as in step 162.

According to this embodiment, detection of serial transmission abnormality can be realized by time monitoring by software in the control CPU 13, and since the serial transmission processing is executed, the parallel transmission processing can be executed, so that the load on the control CPU 13 is reduced. As a result, the execution of the present invention is possible with one control CPU. As a result, the audio synthesizer 10 itself can be significantly downsized, and as shown in FIG. 13, it can be stored in the operation panel 47. As shown in FIG.

As described above, in the present embodiment, not only the accuracy of the announce to the passenger 48 described above, but also the miniaturization and low cost of the device itself can be realized.

In the above embodiment, the error is determined by the reception time interval of the address allocated to the speech synthesis apparatus 10 as an abnormal condition of serial transmission. However, the transmission format error by the serial transmission receiver as a general means of abnormal detection of serial transmission is described. This is also determined by the detection of a parity error, a transmission code error or an abnormality caused by the number of occurrences of the error.

In addition, if the speech synthesis apparatus 10 itself is operated by battery driving by a battery or the like when the elevator control device is powered down, and is executed by monitoring the status of serial transmission when an announce is performed, the power loss signal previously required is lost. It becomes unnecessary.

In addition, since it is necessary to read the power loss signal in the past, the battery capacity can also be accommodated in the operation panel 47, since a DC capacity of about 24V can be realized at about DC 5V.

Next, the third and fourth aspects of the present invention will be described.

An embodiment employing the present invention will be described using FIG. 17 and FIG.

In a recent elevator, the speech synthesis apparatus 10 itself can be incorporated into the operation panel 19 in the elevator cabin 18.

With such a configuration, the voice synthesis apparatus 10 can be connected only with a twisted pair wire for data transmission and a power wire which is a general electric wire, so that the system can be simplified.

Therefore, the place below the position indicator 23 of the elevator or the call button 20 in the elevator cabin 18 is optimal.

In this case, it is necessary to make the external shape of the speech synthesis apparatus 10 about 100 mm x 100 mm x 20 mm in size.

In order to realize this, it is assumed that the voice guide speaker 27 and the voice synthesis device 10 are integrated to be housed in the speaker case 39.

In order to realize this configuration, as shown in FIG. 18, the substrate 51 of the audio synthesizing apparatus 10 is attached to the bottom cover of the speaker case 39.

In this case, since the magnet of the speaker has a thickness of 15 mm, it is necessary to lay out the low-key part 52 at the substrate position where the magnet is located. What is necessary is just to arrange | position the normal IC 53 in the place other than a magnet. Moreover, since the board | substrate 51 itself of the audio | voice synthesis apparatus 10 cannot be attached to the box side of the operation panel 19, it becomes the form which attaches the insulating board 54, such as bakelite, to the back of the board | substrate 51. FIG. In addition, the material of the speaker case 39 is not made of metal, but ABS resin or the like must be adopted to have a structure in which sound is not broken.

19 is an external view of the speech synthesis apparatus 10. As shown in FIG. It can be seen that the voice guide speaker 27 is in a sealed configuration in the speaker case 39 without being seen from the outside as shown by a dotted line. The hole in the front of the speaker case 39 is a negative output hole for the voice guide speaker 27, and generally, an area of about 10% of the speaker area is required.

In FIG. 17, the interphone 24 is generally provided on the upper part of the control panel 19, and the interphone speaker 29 is attached to the interphone speaker 28 below.

The interphone microphone 29 may use a microphone having a directivity of about 60 degrees toward the front of the operation panel 19 so that the voice of the elevator passenger can be captured.

In this embodiment, the voice synthesis apparatus 10 is provided at the rear of the interphone 24.

The interphone 24 itself is a sealed structure, and the internal circuit shown in FIG. 4 functions as a built-in, but the vibration of the sound output from the voice guidance speaker 27 is not transmitted to the interphone 24. 24) Neither the voice synthesizer 10 deteriorates the sound quality.

According to the present embodiment, since the voice synthesis apparatus 10 integrated with the voice guidance speaker 27 is installed at the rear of the interphone 24, the present invention does not affect the control of the present invention of the interphone 24, which is an advantage of the present invention. Not only that, but also the sound output from the voice guide speaker 27 can obtain a good sound quality.

In addition, since the speech synthesis apparatus 10 integrated into the speaker case 39 can be configured, the speech synthesis apparatus 10 itself can be miniaturized.

The design of the operation panel 19 in the elevator cabin 18 does not need to think of the voice guidance speaker 27, so that it is possible to unify the general elevator that does not attach the voice guidance speaker 27 to the operation panel 19.

Moreover, this can handle the structure of the operation panel 19 which had conventionally attached two speakers by having no voice guide speaker 27, and can contribute to the miniaturization of the operation panel 19 itself.

In FIG. 3, the configuration of installing the voice guidance speaker 27 in the downward direction of the operation panel 19 in FIG. 8 is shown. However, the voice guidance speaker 27 is provided with an angle in the transverse direction of the operation panel 19. ) And the interphone speaker 28 may be provided together. In this case, the angle should be about 150 °, and the angle does not affect the design of the elevator.

In the fourth means, the configuration for installing the voice synthesis device 10 behind the interphone 24 is described in FIG. 17, but the speaker case 39 and the voice guide speaker 27 are replaced with the voice synthesis device 10. In FIG. May be a unitary configuration.

In this case, the voice synthesis processing unit is provided on the elevator lift chamber 18.

According to the present invention, since the holding function for the elevator user can be set to one device, the sound or sound output at the optimum position can be seen from the user side. Thereby, there exists an advantage that it can reliably hold | maintain even in a noisy place.

Similarly, a device that is not affected by the size of a user interface device (for example, a call registration device, a display device, etc.) can be provided and can be made in a small shape, and there is an advantage of being easy to store.

Naturally, it can also manufacture cheaply compared with the former.

In addition, the present invention uses an IC which will improve the degree of integration in the future, and therefore has the possibility of making it smaller in the future.

Further, the present invention not only provides an excellent speech synthesis apparatus capable of solving the discontinuity of an abnormal occurrence signal and a general signal, which is a problem in the conventional apparatus, but also announcing an abnormality in an elevator, and employing the present invention. As a result, the device itself can be miniaturized. As a result, the voice synthesizer, which has conventionally required about 180 mm x 180 mm x 50 mm, can be downsized to about 180 mm x 100 mm x 20 mm in a configuration including a speaker, and accommodated in the operation panel 19 in the elevator cabin. Could. As a result, the passenger of the elevator can announce at an easy-to-understand position, so that it is possible to solve the unintelligible sound from the elevator as in the prior art.

Not only that, but at low cost, this function can be realized.

Further, according to the present invention, it is possible to solve the acoustic effects of the interphone microphone and the voice guide speaker, which have been a problem in the conventional apparatus.

Further, by adopting the present invention, the device itself can be miniaturized. As a result, the voice synthesizer, which has conventionally required about 180 mm x 180 mm x 50 mm, can be downsized to about 100 mm x 100 mm x 20 mm in a configuration including a voice guide speaker, and stored in an operation panel in an elevator cabin. It can work.

As a result, an effect can be obtained that the passenger of the elevator can announce at an easy-to-understand position, and at the same time, the present function can be realized at low cost.
